SAN FRANCISCO - RackSaver Inc., which sells servers and software used to build high performance computing clusters, has acquired systems management software vendor MPI Software Technology Inc., it announced Monday. RackSaver has also changed its name to Verari Systems Inc., effective immediately.

The name change and the acquisition, which was completed at the end of March for an undisclosed amount of cash and stock, is part of Verari's plan to become more of a complete systems vendor, said Chief Executive Officer Dave Driggers.

Verari plans to combine its own BladeView and RackView systems management software with MSTI's cluster management products, creating an integrated product that will be called Verari Command Center, the company said.

San Diego-based Verari has sold high-performance computing clusters based on Intel Corp.'s and Advanced Micro Devices Inc.'s processors to a variety of university, research, and enterprise customers including The Boeing Co. and Pixar Animation Studios Inc. With the acquisition of MSTI, which is based in Birmingham, Alabama, it will swell from 200 to 260 employees, Driggers said.

MSTI also has offices in Nashua, New Hampshire, as well as in India and Bulgaria, all of which are expected to remain in operation. "We won't be closing anything," said Driggers. "We'll be adding additional staff in all of the locations, probably."

Also Monday, Verari announced it had hired Masood Jabbar as an adviser to its management team, Driggers said. Jabbar, who was formerly president of computer systems and executive vice president of global sales at Sun Microsystems Inc., will also serve as a director on Verari's board.
